Application May 28, 1937, Serial No. 145,362

1 claim (ci. 2er-s2) ,This invention relates to tooth powder dispensers and has for an object to provide a device of this character having a spring pressed cut ofi valve adapted to be opened by pressure of the tooth brush to permit the tooth powder gravitating onto the ltooth brush without waste.

A further object is to provide a tooth powder dispenser having a measurirg valve assembled with the cut off valve for permitting of a. measured quantity of tooth powder being dispensed each time the cut off valve is opened.

A further object is to provide a device of this character having a guard in advance of the cut off valve for preventing a wet tooth brush from contact With the tooth powder in the dispensing l opening.

A further object is to provide a device of this character which will be formed of a i'ew strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter:

fully described and claimed, it being understood that various modcations may be resorted to `within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification, y

Figure 1 is a longitudinal sectional view of a tooth powder dispenser constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view of the tooth powder dispenser taken on the line 2-2 of Figure 1.

Figure 3 is a longitudinal sectional view of a modied form of the dispenser showing the cut off valve equipped with the measuring valve.

Referring now to the drawing in which like characters of reference designate similar parts in the Various views, I0 designates a base which may be formed of Bakelite or other suitable material and maybe formed of two similar parts to permit assembly of the mechanism, the 'parts being secured together by boltsv or other suitable connectors.

The base is provided in its top with a powder receiving recess II, having a cylindrical side wall and having a bottom wall tapering in the direction of an elongated discharge opening I2. A glass jar I3, or metal container, is provided with a neck I4 which is screw threadedly engaged with the cylindrical wall of the recess II.

The base is also provided with openings I5 toreceive the handles of tooth brushes I6.

A tooth brush receiving opening Il is formed in the base, the opening being of the general shape shown in Figure 1 and extending to and 5 past the discharge opening I2 as best showndn Figure 2. A cut oi valve I8, preferably formed of a hollow casing of the sameshape as the recess II, is provided with a stem I9 which is slidably tted in a combined guide land stop washery 10 20 which is imbedded in the base across a bore 2| into which the bore of the stem extends when the valve is opened by pressure of a tooth brush I6 against the front side of the valve. When the valve is open the tooth powder may gravitate 15 on to the center of the brush in sufficient quantity to permit cleansing the teeth without waste.

A spring 22 is sleeved on the stem between the valve and the washer, and normally holds the valve in position to seal the discharge opening 20 from thel powder and brush receiving recess Il in the base.

A guard 23 is secured to' the cut off valve I8 at the top thereof in advance of the dispensing opening I2. The guard is in the nature of an 25 arcuate plate, as best shown in Figure 1., having a spout 24 which performs the dual function of preventing wet bristles of a tooth brush from entering the dispensing opening I2 and also permits the powder to be dispensed from the open- 30 ing in a thin stream longitudinally on the center of the brush.

An opening 25 is formed in the base to receive any suitable supporting bracket or other securing device for mounting the device upon a wall. 35 However, the device may be simply supported upon a table, shelf l or other suitable support without resorting to a securing bracket.

A modified form of the invention is shown in "Figure 3 in which the base 26 is similar to the 40 powder.

The novel feature of the form of the invention shown in Figure 3 is a measuring valve 32 50 which is slidably fitted in a slot 33 which is formed in the base above and parallel to the brush receiving opening 2'I. The valve is provided with a port 34 and beyond the port the valve is secured to the cut off valve 29 by a ver- 55 tically disposed bracket arm 35 which is slidably fitted in a recess 36 which communicates with the rear end of the brush receiving opening 21 at the top thereof. The cut oi valve 29 is provided with va combined guard and dispensing nozzle 31 as previously described.

In operation, in the modied form of the invention, when the cut of valve is in closed position the port 34 of the measuring valve 33 permits a predetermined quantity of tooth powder to collect in the dispensing opening 28 and open the top of the cut oi valve. When the cut off valve is pushed open by a tooth brush, as previously described, the measuring valve 33 is slid rearwardly as a unit with the cut ofi' valve and seals the discharge opening so that only the desired quantity of tooth powder may be dispensed on the tooth brush.

From the above description it is thought that the construction and operation of the invention will be fully understood Without further explanation.

What is claimed is:

A powder dispenser comprising a base having a powder receiving recess in the top, a powder container having a neck screw threadedly engaged in said recess, there being a brush receiving opening in the base intercepting said re'- cess, a valve in said opening, a stem for the valve receivable in a. bore in the base formed in axial alignment with said opening, a spring sleeved on the stem for normally' holding the valve to close the recess, pressure of a brush in said opening being adapted to dislodge the valve to unseal the recess, and a guard integral with the valve and having a spout providing a discharge opening adapted to register with said recess when the valve is opened, said spout preventing contact of the brush with the walls of saidv recess.
